It says something that Microsoft is the only company that has been sued so far. May be Apple will be next, but these are the companies that initiate patent wars against their competitors. Now that the companies are hitting back, you think it is a bad precedent ? I'd be more worried if they start doing it to smaller companies than giants like these.
